This week went by rather quickly. The kids have started with some geometry in math. I think they enjoy the break from decimals and percents. On Friday, we did a little experiment with eggs, vinegar, and toothpaste. We were trying to demonstrate how toothpaste protects your teeth from the acids in food.
One egg was covered in toothpaste the night before and allowed to dry. The next day, we wash off the toothpaste and put both eggs in vinegar. We observed the eggs throughout the day. The one with the "x" had no toothpaste and the shell deteriorated quickly.
